5. CONCLUSION
We determined that microscopic hematuria was associated with stone size and hydronephrosis severity. Unlike other studies, we found a higher rate (17.9%) of renal colic due to ureteral stone in patients without microscopic hematuria. If a patient with suspected ureteral stone disease does not have microscopic hematuria, we consider that non-contrast CT imaging is necessary for diagnosis and treatment, since the size of the stone may be larger and the degree of hydronephrosis may be more severe.
